Although they are polymorphic(multiphase)materials,both copper and silver are reliable Hugoniot standards,and thus it is necessary to establish an accurate analytic model of their principal *** we present analytic forms of their principal Hugoniots,as well as those of iridium and platinum,two“pusher”standards for shock-ramp experiments,over a wide range of *** are based on our new analytic model of the principal Hugoniot[Burakovsky et al.,***.132,215109(2022)].Comparison of the four Hugoniots with experimental and independent theoretical data(such data exist to very high pressures for both copper and silver)demonstrates excellent ***,the new model for copper and silver can be considered as providing the corresponding Hugoniot standards over a wide pressure *** also suggest an approach for calculating the Grüneisen parameter along the Hugoniot and apply it to copper as a prototype,and our results appear to be in good agreement with the available data.

A Comparison between 2D and 3D Images to Study Maxillary and Mandibular Widths: A Pilot Study

引用

Open Journal of Stomatology 2017年第3期7卷 186-196页

作者： Ilaf Al Mawaldi Sawsan Tabbaa C. Brian preston Mayssa Salti Department of Orthodontics School of Dental Medicine SUNY at Buffalo New York USA School of Orthodontics Brooks Rehabilitation College of Healthcare Jacksonville University Florida USA Department of Orthodontics School of Dental Medicine SUNY at Buffalo New York USA Post-Graduate Program Department of Orthodontics School of Dental Medicine SUNY at Buffalo New York USA

The objective of this study is to compare the transverse dimensions of the jaws, obtained from traditional posteroanterior (PA) cephalometric radiographs, and with the similar respective measurements obtained by means of cone beam computed tomography (CBCT). Data of twelve subjects were selected from the clinical records of Orthodontic Department. All of the subjects had their permanent teeth in occlusion and had good quality regular (2D), and CBCT (3D) images as part of their initial records. Subjects were divided to a posterior cross-bite and non-cross bite groups. The ratio of the maxillary, to mandibular transverse widths was calculated for the sample. In subjects without dental cross-bites the average ratio of the maxillary, to mandibular jaw widths was 0.75 on the standard radiographs and 1.04 on the CBCT scans. In subjects with dental cross-bites the average ratio of these widths was 0.70 on the standard radiographs and 0.9 on the CBCT scans. The ratios of the maxillary, to mandibular widths differ when obtained from conventional cephalometric radiographs as compared to the respective ratios obtained from CBCT scans. Maxillary, to mandibular width ratio is in the order of 1:1 as determined by means of CBCT scans.
